after trying, googeling and failing over and over again I decided to ask for your help in your forums. I'd like to install Warcraft 3 The Frozen Throne with the Blizzard app on my computer using Ubuntu 18.04.3, bionic. .
First I tried wine from the Ubuntu standard repositories, but it didn't work. Someone told me then to use Wine-staging, so I removed the old wine and installed wine-4.17 (Staging)
I followed the instructions provided by your website: https://wiki.winehq.org/Ubuntu
The installation wasn't without obstacles and after investigating some more time, I figured that I needed to add another repository in order to get some lib file which is not in the Ubuntu sources as well.

After this I was able to get wine running. So I tried running the Blizzard app with wine $ wine64 Warcraft-III-Setup.exe
The app started and let me choose a language, but then it displays a error message and that's it : https://imgur.com/a/wC5FlLu
